<p>PURPOSE:To serve as well with a single switch and to reduce a space for an operation panel by actuating in order a multistep storage means by the output of an operation switch and using the output of each step of the multistep storage means as the control signal for a controlled system device. CONSTITUTION:A contact X2 makes with a 1st time depressing of a button switch PB, a power source is given to a motor 3 from a power source 9 and a standby state is attained with the rotation of the motor 3. A contact X4 makes with a 2nd time depressing of the switch PB, the solenoid valve 5a of a transmission part 5 is actuated, driving wheels 4a, 4b are rotated and a traveling rail 2 moves with placing a bolster 6 thereon. When a running is started, the limit switch LS7 provided on the traveling rail 2 is actuated by its coming upon a base 1 and the output of the switch LS7 is inputted to a control part 7. A limit switch LS8 is actuated when the bolster 6 is moved up to the work position of a press and the output of the switch LS8 is inputted to the control part 7. The respective such state is displayed by the single display lamp of the operation panel.</p> |
